[Tests-Only] Run litmus CI for both owncloud and ocis storage

[phil-davis]

Test both ocis and owncloud storage with litmus.

(after this is merged, I will then work on running the API tests with ocis storage as well as owncloud storage)

[phil-davis]

PR #1155 introduced ocis storage.

@butonic this PR runs litmus tests on both owncloud and ocis storage. owncloud passes (like it already did). ocis storage fails:

old webdav:

Is there a known issue with copying/moving a collection/folder?

[phil-davis]

I cherry-picked from PR #1177 into here - to demonstrate that litmus now passes for ocis storage.

[phil-davis]

Now litmus fails in a different way: https://cloud.drone.io/cs3org/reva/2566/3/5 (ocis old webdav)

13. propreplace........... 
13. propreplace........... FAIL (PROPPATCH on `/remote.php/webdav/litmus/prop2': 500 Internal Server Error)

14. propget............... 
14. propget............... FAIL (Property {http://example.com/neon/litmus/}prop9 had value value9, expected newvalue9)

15. propnullns............ 
15. propnullns............ pass

16. propget............... 
16. propget............... pass

17. propremoveset......... 
17. propremoveset......... FAIL (PROPPATCH remove then set)

18. propget............... 
18. propget............... FAIL (No value given for property {http://example.com/neon/litmus/}removeset)

And https://cloud.drone.io/cs3org/reva/2566/5/5 has the same fails for ocis new webdav.

This is after PR #1177 "fix ocis move" was merged.

I raised issue #1178

[phil-davis]

PR #1179 fixed the fails. I rebased, so this should pass now.

[phil-davis]

@ishank011 CI should pass here now - please review.
